MDINT(MII Transaction Complete When set, indicates that a transaction (read or write) on the MII interface has completed successfully.)
在使用LM3S862时发现如下情况:以太网控制器初始上电后进行了MII读写操作各一次,之后再未对MII窗口做任何读写操作 即Ethernet MAC Management Control (MACMCTL)寄存器的START位并未置位,但是出现会反复产生MDINT中断,产生MDINT中断后清除中断标志同样反复会有MDINT中断。
请问MDINT中断产生的因素有哪些,难道还有数据手册上未提及情况下会产生MDINT中断?
